Russia finds 40% of its Chinese chip imports are defective
Posted by Raphael Ramos in category: computing
As reported by The Register, pro-Putin newspaper Kommersant writes that the percentage of defective imported chips into Russia before the war was just 2%, which isn’t very good considering how many components are found in today’s electronic items. Now, almost eight months after the country invaded Ukraine, it stands at 40%.

Antidote saved 100% of bees from lethal pesticide

Immunizing bees against pesticides.
‘We wanted to develop a strategy to detoxify managed pollinators and found we can do it by incorporating it into their food, senior author Minglin Ma, a biomaterials engineer at Cornell University told Chemistry World.
“Managed bee colonies are constantly in need of being replenished due to losses. This relieves the stress for beekeepers to meet the ever-increasing demand for pollination,” James Webb, also a co-author of the study, told Salon by email.

The Many-Worlds Theory, Explained
Posted by Dan Breeden in categories: information science, particle physics, quantum physics
Quantum physics is strange. At least, it is strange to us, because the rules of the quantum world, which govern the way the world works at the level of atoms and subatomic particles (the behavior of light and matter, as the renowned physicist Richard Feynman put it), are not the rules that we are familiar with — the rules of what we call “common sense.”
The quantum rules, which were mostly established by the end of the 1920s, seem to be telling us that a cat can be both alive and dead at the same time, while a particle can be in two places at once. But to the great distress of many physicists, let alone ordinary mortals, nobody (then or since) has been able to come up with a common-sense explanation of what is going on. More thoughtful physicists have sought solace in other ways, to be sure, namely coming up with a variety of more or less desperate remedies to “explain” what is going on in the quantum world.
These remedies, the quanta of solace, are called “interpretations.” At the level of the equations, none of these interpretations is better than any other, although the interpreters and their followers will each tell you that their own favored interpretation is the one true faith, and all those who follow other faiths are heretics. On the other hand, none of the interpretations is worse than any of the others, mathematically speaking. Most probably, this means that we are missing something. One day, a glorious new description of the world may be discovered that makes all the same predictions as present-day quantum theory, but also makes sense. Well, at least we can hope.

New tool allows scientists to peer inside neutron stars
Posted by Quinn Sena in categories: information science, physics, space
Imagine taking a star twice the mass of the sun and crushing it to the size of Manhattan. The result would be a neutron star—one of the densest objects found anywhere in the universe, exceeding the density of any material found naturally on Earth by a factor of tens of trillions. Neutron stars are extraordinary astrophysical objects in their own right, but their extreme densities might also allow them to function as laboratories for studying fundamental questions of nuclear physics, under conditions that could never be reproduced on Earth.
Because of these exotic conditions, scientists still do not understand what exactly neutron stars themselves are made from, their so-called “equation of state” (EoS). Determining this is a major goal of modern astrophysics research. A new piece of the puzzle, constraining the range of possibilities, has been discovered by a pair of scholars at IAS: Carolyn Raithel, John N. Bahcall Fellow in the School of Natural Sciences; and Elias Most, Member in the School and John A. Wheeler Fellow at Princeton University. Their work was recently published in The Astrophysical Journal Letters.
